Just as a rule of thumb that I’ve noticed between a few major brands;
B&W = good bass, thin mid-range, mildly bright and detailed tweeter, very wide and tall sound stage.
Focal = thinner bass, thin mid-range, bright and very detailed tweeter
Sonus Faber = bass similar to Focal, fullest mid-range, mildly bright and detailed tweeter
I consider Sonus Faber being the all around average or middle ground between the others. Older generations might be slightly different due to tuning changes.
